[counterintuitive] chain of thought always improves reasoning

Evaluate CoT on a per-task basis; avoid CoT for tasks requiring strict formatting, simple memorization, or where intermediate reasoning steps introduce compounding errors.

Journey Context:
Chain-of-thought \(CoT\) is treated as a universal accuracy booster. However, for tasks where the model already has strong intuitive prior \(memorization\), forcing it to reason step-by-step can disrupt the correct answer. Furthermore, CoT can cause the model to hallucinate an intermediate step that is logically flawed, which it then uses to justify an incorrect final answer. CoT is a tool for computation, not a universal accuracy dial.
